This photosensitive material is processed by a stage having washing and/or stabilizing processing. An automatic developing machine is used in this processing method and the discharge liquid volume in the circulation of the washing and/or stabilizing liquid in the washing and/or stabilizing bath is specified to 30 to 200% of the volume of the washing and/or stabilizing bath liquid per 1 minute. In addition, the flow velocity of the discharge liquid is specified to >=20m per 1 minute. Thus, the preservable property of the photosensitive after the processing is improved and the images having the good after-color characteristic are obtd. This effect is exhibited even in the case of the short-time processing.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for processing silver halide photographic materials. In particular, the present invention relates to a method for processing a silver halide photographic material that has good residual color and can improve the storage stability of the processed light-sensitive material.

[Conventional technology]

Conventionally, in the field of silver halide photographic materials, there has been a demand for shortening processing time to enable rapid processing.

For example, in the field of printing plate making, work efficiency and rationalization are progressing, and accordingly, there is a demand for shortening the processing time of photosensitive materials for printing. In order to meet such demands, shortening of processing time is being considered.

However, if the processing length is shortened or the processing line speed (transport speed during processing of the photosensitive material to be processed) is increased in order to shorten the processing time, a number of problems arise. In particular, there is the problem of residual color in that the dye that should be removed remains on the processed photosensitive material, and the problem of poor storage stability of the processed photosensitive material.

[Purpose of the invention]

The present invention solves the above-mentioned problems of the prior art and provides a method for processing silver halide photographic light-sensitive materials that can improve the residual color and the storage stability of the light-sensitive material after processing even when processing is performed for a short time. This is what I am trying to do.

[Means for solving problems]

As a result of intensive research, the present inventors have found that the support has at least one hydrophilic colloid layer on each side, that the hydrophilic colloid layer is free from gelatin, and that the amount of gelatin applied is 3 to 3 ml per side of the support. A processing method in which a silver halide photographic light-sensitive material having a weight of . The amount of liquid discharged for water washing and/or stabilization liquid circulation in the bath should be 30 to 200% of the amount of water washing and/or stabilization bath liquid per minute, and the flow rate of the discharged liquid should be 20 m per minute or more. The present invention has been completed based on the discovery that the above-mentioned objectives can be achieved by a method for processing silver halide photographic materials characterized by the following.

Although the effects of the present invention are not necessarily clear, it was unexpected and surprising for the present inventors that the various quantitative aspects of the present invention were achieved by the above configuration.

The present invention will be explained in more detail below.

The photosensitive material to be processed to which the processing method of the present invention is applied has at least one hydrophilic colloid layer on each side of the support. There are various hydrophilic colloid layers such as a silver halide emulsion layer, a backing layer, a protective layer, an intermediate layer, and an antihalation layer. Therefore, the light-sensitive material may have a structure in which it has at least one silver halide emulsion layer on one side of the support and, for example, a backing layer on the opposite side; Each layer may have at least one silver halide emulsion layer. Non-photosensitive layers such as a protective layer, an intermediate layer, and an antihalation layer other than the silver halide emulsion layer, which are formed as necessary, may be formed with a layer structure depending on the properties of each layer.

The silver halide emulsion layer may be formed by laminating two or more layers.

In the present invention, the hydrophilic colloid layer consists of gelatin. Here, "consisting of gelatin" means that it essentially contains gelatin as a hydrophilic colloid. Regarding the silver halide emulsion layer, the hydrophilic colloid that functions as a binder is primarily gelatin. Gelatin as used herein also includes gelatin derivatives.

Next, in the photosensitive material to be processed in the present invention, the amount of gelatin applied on one side of the support is 3.5 g/rrr or less.

Preferably, the amount of gelatin applied is 3.0 g or less, more preferably 2.8 g or less, even more preferably 2.5 g or less.

The photosensitive material to be processed preferably has a swelling rate, especially a swelling rate after fixing, of 150% or less, more preferably 100%.
The following are more preferable.

Here, the swelling rate is as follows: (a) The photosensitive material to be processed is heated at a temperature of 25°C and a relative humidity of 50%.
(b) Measure the thickness of the hydrophilic colloid layer, (C) Normally process with a developing/fixing means using the photosensitive material, and (d) In step (b) above. It can be determined by measuring the percentage change in the thickness of the layer compared to the measured thickness of the hydrophilic colloid layer.

Further, the amount of coated silver is preferably 3.0 g/rd or more, more preferably 3.5 g/n (or more), in which case the effect of the present invention can be further enhanced.

It is preferable that at least one silver halide emulsion layer of the photosensitive material to be processed contains silver halide grains having a (100) plane/(111) plane ratio of 5 or more.

Such particles may have 100% (100) planes.

The (100) plane/(111) plane ratio of the particles can be measured by Kubelkamunk's dye adsorption method. In this method, a dye is preferentially adsorbed to either the (100) plane or the (111) plane, and the association state of the dye on the (100) plane and the association state of the dye on the (111) plane are spectrally different. Select and use. The (100) plane/(111) plane ratio can be determined by adding such a dye to an emulsion and examining the spectra in detail with respect to the amount of the dye added.

The detailed ratio of (100) planes on the silver halide grain surface is as follows:
Tadaaki Tani, “Identification of crystal phase of silver halide fine grains in photographic emulsions using dye adsorption phenomenon,” Journal of the Chemical Society of Japan i, 942
~946 (1984).

Silver halide grains having a (100) plane/(111) plane ratio of 5 or more can be prepared by various methods. In general, the pAg value during grain formation is kept at a constant value of 8.10 or less, and a silver nitrate aqueous solution and an alkali halide aqueous solution are simultaneously added at a rate that is faster than the dissolution rate of the particles and at which re-nucleation is large. It can be preferably prepared by the double jet method. More preferably, the PAg value is 7.80 or less, and even more preferably, the PAg value is 7.60 or less. Silver halide grain formation is called nucleation and its growth.
When divided into two processes, there is no restriction on the PAg value during nucleation, and the PAg value during growth is preferably 8.10 or less, more preferably 7.80 or less, and still more preferably 7.60 or less. good. Although the soluble silver salt and the soluble halogen salt may be reacted by a one-sided mixing method, a simultaneous mixing method is better in order to obtain good monodispersity.

Here, when it is 32 or less, it also includes the case that the liquid amount is zero, that is, no liquid replenishment is performed.

If this replenisher is used, it becomes possible to save water and also to eliminate the need for piping for an automatic developing machine. Furthermore, the number of stock tanks can be reduced.

That is, the washing water (and diluting water for the developing solution and fixing solution, if necessary) or the stabilizing solution can be supplied from one common stock tank, making it possible to further downsize the automatic developing machine.

Note that the case where the replenishment amount of the washing water (or stabilizing liquid) is zero means a washing method using a so-called water washing method.

In the present invention, the concentration of calcium compounds in the replenisher during washing and/or stabilization treatment is 10/I! as calcium ions. , or less is preferable. More preferably 5■/I! , below, more preferably 3
It is less than ■/i, particularly preferably less than 1 ■/l.

Various means can be used to adjust the concentration of calcium in the replenisher in the water washing treatment or stabilization treatment to the above level. Preferably, ion exchange resins and/or reverse osmosis equipment are used.

Although various cation exchange resins can be used as the ion exchange resin, it is preferable to use a Na type cation exchange resin in which Ca is replaced with Na.

Further, an H-type cation exchange resin can also be used, but in this case, the pH of the treated water becomes acidic, so it is preferable to use it together with an OH-type anion exchange resin.

The ion exchange resin is preferably a strongly acidic cation exchange resin having a styrene-divinylbenzene copolymer as a base and having a sulfone group as an ion exchange group. Examples of such ion exchange resins include Mitsubishi Kasei's product name Diaion 5K-IB or Diaion PK-2.
I can list 16 etc. 1. The substrate for these ion exchange resins is preferably one in which the amount of divinylbenzene charged is 4 to 16% based on the total amount of monomers charged during production.

Examples of anion exchange resins that can be used in combination with H-type cation exchange resins include strong basic anion exchange resins that have a styrene divinylbenzene copolymer as a base and a tertiary amine or quaternary ammonium group as an exchange group. preferable. An example of such anion exchange resin is Diaion 5A, also manufactured by Mitsubishi Kasei.
-1OA or Diamondion PA-418.

As the reverse osmosis treatment device that can be used, any known one can be used without limitation, but the area of the reverse osmosis membrane is 3rrf or less, the working pressure is 30kg/nf or less, particularly preferably 2rrr or less, 20kg/rrf or less It is desirable to use a very small device. When such a small device is used, the workability is good and a sufficient water saving effect can be obtained. Furthermore, it is also possible to pass activated carbon or a magnetic field.

Note that as the reverse osmosis membrane included in the reverse osmosis treatment device, cellulose acetate membrane, ethyl cellulose/polyacrylic acid membrane, polyacrylonitrile membrane, polyvinylene carbonate membrane, polyether sulfone membrane, etc. can be used.

In addition, although a liquid feeding pressure of 5 to 60 kg/c1M is normally used, a pressure of 30 kg/cdl or less is sufficient to achieve the purpose of the present invention, and a so-called low-pressure reverse osmosis device with a pressure of 10 kg/c1a or less is also sufficient. Can be used.

The structures of reverse osmosis membranes include spiral type and tubular type.
Any of the mold, hollow fiber type, pleated type, and rondo type can be used.

In the present invention, the concentration of the magnesium compound in the replenisher in the water washing and/or stabilization treatment is preferably 10@Z/f or less as magnesium ions, more preferably 5@Z/l or less.

In order to control the amount of magnesium compound in the replenisher as described above, the means for controlling the amount of calcila compound described above can be similarly used.

In the present invention, washing with water means washing with water components of the processing liquid attached to or occluded in the photosensitive material to be processed, components of the photosensitive material that are no longer needed during the processing process, and the like. Therefore, this can be said to be a process for ensuring performance after processing.

Further, in the present invention, the stabilization treatment is a step of improving the storage stability of an image to a level that cannot be obtained by washing with water, and is comprised of a liquid containing a component having an image stabilizing effect in -a.

As the washing or stabilization treatment, any method known in the art can be applied, and water containing various additives known in the art can also be used as the washing water or stabilizing liquid. For example, water treated with anti-mold measures can be used as a washing or stabilizing liquid.

When water treated with anti-mildew treatment is used in combination with washing or stabilizing liquid, the formation of water scale can be effectively prevented.
For example, water saving treatment of O to 3, preferably O to 12, can be performed.

As a method of reducing the amount of replenishment, a multistage countercurrent system (for example, two stages, three stages, etc.) has been known for a long time. If this multi-stage countercurrent method is applied to the present invention, the photosensitive material after fixing will be processed in a progressively cleaner direction, that is, in sequential contact with the processing solution that is not contaminated by the fixer, resulting in even more efficient processing. Water washing or stabilization is performed. According to this, unstable thiosulfates and the like are appropriately removed, the possibility of discoloration and fading is further reduced, and an even more significant stabilizing effect can be obtained.

The amount of water used for washing is also much smaller compared to conventional methods.

When washing with a small amount of water, patent application 1729/1986
It is more preferable to provide a squeeze roller cleaning tank as described in No. 68.

Furthermore, anti-mildew measures can be applied to the washing or stabilizing bath.

In this specification, "development time" and "fixing time" refer to the time during which the photosensitive material to be processed is substantially in contact with the developer and fixer, respectively, and the photosensitive material is in the developing tank of an automatic processor. It refers to the time from immersion in a liquid to the time of immersion in the next fixing liquid, and the time from immersion in a fixing tank liquid until immersion in the next washing tank liquid (stabilizing liquid).

Further, "washing time" refers to the time during which the product is immersed in the washing bath liquid.

Furthermore, "drying time" refers to the automatic processing machine that is equipped with a drying zone where hot air is normally blown at 35°C to 100"C, preferably 40°C to 80"C. This refers to the time spent.

The development temperature and time are preferably about 25°C to 50"C for 15 seconds or less, more preferably 30°C to 40"C.
5 seconds to 15 seconds at 5°C.

Examples of the fixing solution include sodium thiosulfate and ammonium thiosulfate, but it generally contains thiosulfate ions and ammonium ions, and ammonium thiosulfate is particularly preferred from the viewpoint of fixing speed. The amount of fixing agent used can be varied as appropriate, and is generally about 0.1 to 056 mol/l.

In the present invention, the fixer may contain an acidic hardener. Furthermore, tartaric acid, citric acid, or derivatives thereof can be used alone or in combination of two or more kinds in the fixer. Generally preferably, these compounds are present in fixer solution 1.
Those containing 0.005 mol or more per 1 are effective, especially 0
．． Particularly effective is 0.01 mol/l to 0.03 mol/l.

Specific examples include tartaric acid, potassium tartrate, sodium tartrate, potassium sodium tartrate, citric acid, sodium citrate, potassium citrate, lithium citrate, and ammonium citrate.

The fixer may optionally contain preservatives (e.g. sulfites, bisulfites), pH buffers (e.g. acetic acid, nitric acid), pHI
It can contain a conditioner (for example, sulfuric acid), a chelating agent with water softening ability, and a compound described in Japanese Patent Application No. 60-213562.

The fixing temperature and time are preferably about 20"C to about 50"C and 15 seconds or less, more preferably 30C to 40C and 5 seconds to 15 seconds.

When a fixer concentrate is used and dilution water is used, the fixer i4 condensate is usually composed of two agents, but may be composed of one agent.

The fixer stock solution can stably exist as a single agent at a pH of 4.5 or higher, more preferably at a pH of 4.5 or higher.
It is 65 or more. If the pH is less than 4.5, there is a risk that the thiosulfate will decompose and eventually become sulfided, especially if the fixer is left for a long period of time before it is actually used. When the pH is in the range of 4.5 or higher, less sulfur dioxide gas is generated, which improves the working environment. The upper limit of pH is not so strict, but if it is fixed at too high a pH, the pH of the membrane will deteriorate even after washing with water.
A pH of up to 7 is desirable because the H content increases, membrane swelling increases, and therefore the drying load increases.

In the present invention, it goes without saying that the developer and/or fixer may be a so-called working solution that does not require dilution water (that is, is replenished as an undiluted solution).

When using concentrates, the amount of each concentrate supplied to the processing tank liquid and the mixing ratio with dilution water can be varied depending on the composition of the concentrate, but in general, the ratio of concentrate to dilution water is Preferably, the ratio is 1:0 to 8, and the total amount of each of the developer and fixer is 50 -
to 1500- is preferable.

In the practice of the present invention, a method may be used in which the developed, fixed, and washed photographic material is dried by squeezing out the washing water, that is, by using a squeeze roller method.

Drying can be carried out at a temperature of about 40"C to about 100°C, and the drying time can be changed appropriately depending on the surrounding conditions, but it is usually about 5 seconds to 1 minute, but more preferably 40"C to 80°C.
C for about 5 seconds to 30 seconds.

The present invention exhibits an even more excellent effect of shortening the drying time.

According to the method of the present invention, the so-called dry-to-dry processing time from development, fixing, washing, and drying is 1
The processing time is preferably within 0.00 seconds, and as described above, the processing time is more preferably within 60 seconds, and still more preferably within 50 seconds.

Here, "Dry to Dry" refers to the time from the moment the leading edge of the photosensitive material to be processed enters the film insertion section of the automatic processor to the moment the leading edge emerges from the automatic processor after being processed.
